Step 1: \(CuO\) is reduced to \(Cu\).
Step 2: \(H_2\) is oxidised to \(H_2O\).
Step 3: Hence, it is a **Redox reaction**.

Step 1: \(AgNO_3\) reacts with \(NaCl\) to form \(AgCl\) and \(NaNO_3\).
Step 2: Exchange of ions occurs.
Step 3: Hence, it’s a **Double Displacement reaction**.

Step 1: Zinc displaces hydrogen from sulphuric acid.
Step 2: This is a **Displacement reaction**.

Step 1: A single reactant \(KClO_3\) decomposes into \(KCl\) and \(O_2\).
Step 2: Hence, it is a **Decomposition reaction**.

Step 1: Hydrogen and oxygen combine to form water.
Step 2: Two reactants combine to form one product.
Step 3: Hence, it is a **Combination reaction**.
